Question

The table below lists natural and human-accelerated fluxes within the system. The units of the fluxes billions of metric tons per year. For example, the flux of photosynthesis by plants takes carbon from the atmosphere to plants at a rate of 102 times 109 metric tons/yr. Sources: Houghton, J. Jenkins, G., and Ephraums, J., 1990. Climate Change: The IPCC Scientific Assessment. Cambridge Univ. Press (for UN Intergovernmental Panel on Climate Change). National Research Council, 1986. Global Change in the Geosphere-Biosphere. Washington: National Academy Press. Question How do human-accelerated fluxes affect the total flux of carbon into and out of the plant, fossil fuel and atmosphere reservoirs? For each reservoir, state whether the input or the output increases or decreases (example answer: the output decreases) Plant Fossil Fuel Atmosphere
